OBB disk images: GRID frees the mounted path with its own allocator; skip that free

Device run (one OBB): the mount emulation works ("OBB DataSet0.obb mounted"), then
getOBBMountPoints crashed freeing the long path string libandroid_utils allocated
(Quest's short /mnt/obb path never hits the heap). NativeFix: two branches in libgrid
1.0.0.41, window SHA-256 checked.

Patches that are on by default are on for every game, so the catalog rarely names them.

+"""Games that mount their OBB as a disk image (GitHub #308, GRID Legends): Android's StorageManager.mountObb() asks
+vold to attach the .obb (a FAT image made with Google's jobb tool) to a loop device and mount it; the game then reads
+its data below StorageManager.getMountedObbPath(). Lepton's Android 11 has neither loop devices nor device-mapper
+(`vold: Failed to open loop-control`), so every mount fails with state 21 (ERROR_COULD_NOT_MOUNT) and the game throws
+`RuntimeException: Can't mount OBB …`.
+
+FramePort mounts nothing: the agent unpacks each FAT image on the Frame into a folder *with the image's name*
+(`obb/DataSet0.obb/` instead of the file `obb/DataSet0.obb`; agent `unpack_obb`, after the install), and this patch
+rewrites the game's OBB helper so that "mounting" reports success at once and the "mount point" is that folder, i.e.
+the OBB's own path. The folder keeps the checks that look at the file working (File.exists(), the `.obb` count in the
+OBB folder), the storage cost is the data once (the image is removed after unpacking), and Lepton's read-only bind
+mount of the OBB folder shows it to the game unchanged.
+
+Handlers: only Codemasters' `androidutils.OBBHandler` (GRID Legends; its native side, libandroid_utils.so, already
+accepts a synchronous MOUNTED callback: that is its "already mounted" path) is rewritten so far. Other mountObb users
+are detected (analysis `obb_mount`) and reported, but need their own handler entry (or a dex writer that can add
+methods). The edit is in place (Dex.rewrite_start): `mountOBB(name)` → `onMountOBBStateChanged(1 /* MOUNTED */,
+name); return`, `getMountedOBBFullPath(name)` → `return getOBBFullPath(name)`. unmountOBB stays: in Lepton
+isObbMounted() is false, so it already reports "not mounted" (23), which the game accepts.
+
+Encrypted OBBs (jobb -k: PBKDF2 + Twofish, footer flag OBB_SALTED) are not supported; GRID's are plain FAT32 and the
+game passes no key. FAT is case-insensitive, the Frame's file systems are not: unpacked names keep the image's case
+(GRID's own index.txt uses the same spelling as its files).
